Inclusion set theory
The algebra of sets is the set-theoretic analogue of the algebra of numbers. Just as arithmetic addition and multiplication are associative and commutative, so are set union and intersection; just as the arithmetic relation "less than or equal" is reflexive, antisymmetric and transitive, so is the set relation of "subset". It is the algebra of the set-theoretic operations of union, intersection and complementation, and t… Web39 rows · A is a subset of B. set A is included in set B. {9,14,28} ⊆ {9,14,28} A⊂B: proper …

WebSep 5, 2024 · Theorem 1.1.1 Two sets A and B are equal if and only if A ⊂ B and B ⊂ A. If A ⊂ B and A does not equal B, we say that A is a proper subset of B, and write A ⊊ B. The set θ = {x: x ≠ x} is called the empty set. This set clearly has no elements. Using Theorem 1.1.1, it is easy to show that all sets with no elements are equal.
